The centurion had a different idea. As Jesus approached the centurion, he sent an envoy to Jesus with this message: "I am not worthy." The centurion related that he understood how authority worked and that it was enough for Jesus to simply say the word and his servant would be healed.
He had faith in Jesus and in the authority of Jesus. He did not have faith in himself.
What is your faith in? Your own deservedness? Or in Jesus?
